Hah, I was about to revive this thread as well. I was going through my universities library collection, and they just happened to have this book, so I got it out. It was more out of curiosity than actually for usage; I've still got another month or so until I've added all the kanji.
I was going to ask, to the people who did use the book straight away, do you recommend it now, months (or maybe even years) after you 'completed' it? It definitely looks like a great place to start.
